Yesterday my car my car lost all oil from transmission. However I was ready
to rebuild it, I had already rebuild kit and Chilton's manual. (there was no
4-th gear)

The problem is with Chilton's manual which didn't let me sleep last night, I
found there "trnasmission application chart". There is info that 1991
T-birds and Cougars has A4LD transmission (T letter is identification for
this tranny and also for AOD from previous years)!!.

I couldn't check oil pan because it was late in night.

Please make me sure theat in my car is AOD, I have all parts to rebuild. I'm
not from US and it takes some time to get this parts.

If it is a 5.0L, it should be the AOD. AFIK, the A4LD was
only used behind 6 cylinder engines. The chart I have shows
the AOD for both the 3.8L & the 5.0L engines for 85-92
'Birds. If you have lost 4th gear, it is likely an OD band
failure which is usually a result of low line pressure. The
low line presure is often a result of a damaged bushing
where the transmission throttle cable attaches to the
engine. Make sure you check this and replace with the
updated part. The throttle cable must be properly adjusted
to prevent this and make sure the trans shifts properly.
Otherwise, it will soon fail again. If you intend to do a
proper overhaul of the trans, make sure you have the plastic
seal protectors to install the clutch pack seals. You will
also need a clutch pack compressor to disassemble/reassemble
them. A good low range torque wrench is immensely valuable
in rebuilding this trans as the settings can be critical.
As far as the Chilton manual, you can go ahead and burn it
for what it is worth in this repair. Either get the Ford
factory manual or the ATSG manual for your trans. The tools
and the manual are all available on the net if you run a few
Google searches.

Don't worry about it, the A4LD was used behind the 3.8L V6,
not the 5.0L V8. The "LD" stands for Light Duty...

I am changing fluid right now on my '93 Cougar 3.8L. It has the AOD - the
oil pan has very pretty script "Automatic Overdrive" stamped into it.

A friend's son had the damaged bushing on a '91 Cougar,
knew not what to do, lost tranny function before we
could tell him what to do.

It's one of the damnedest examples of automotive mis-
engineering I've ever seen. Blow a tranny on account of a $2
connector part that was *designed* to fail.

How many years did it go on like that? '89 to '93??

A tip of the hat to lugnut for pointing this out. Things
that are massively illogical don't stick in my memory:
I'd totally forgotten. Of course, I've gotta 4r70w now:
hopefully I'll remember at least some of it's bugaboo's. :-)

Somewhere out there is a poor retiree, fixed income,
no extra $, nursed his old Cougar or 'Boid like a
baby. Tomorrow he/she'll be looking at $750 for a
tranny overhaul?

Well Puddin,
You are talking about a car that is now 10+ years old. When the car was made, that
bushing may have been the latest and greatest compound that ever was. After 10 years
it degraded and fell apart. Who could know? Unless you want that part to be released
in 1981 and then studied until 2001, even then it's 3 years before the studies that
said the compund was ok for TV bushings in 2005..
Ford conceeded to a design flaw that went back (?) years. How far back should it go??

Do you have evidence that it was "latest and greatest"?

I have evidence that it was Junk.

Engineers who properly design autos to last 10+ years,
that's who.

I haven't heard that Ford conceded anything whatsoever. If they did
concede (please provide evidence), how many owners do you think have
heard of it?

Ford has no monopoly on mis-engineering etc. All major car makers
produce some junk, it's just a question of degree. If one can
properly assess degree before purchasing, one can likely avoid
numerous headaches. Caveat Emptor!

If it has a vacuum modulator(small cylinder usually located on top of
transmission housing, with a rubber line going to manifold vacuum on the
engine), it's NOT an AOD.
If it doesn't, it's not an A4LD.

Thanks for help,

Definitely T-bird 1991 5.0 has AOD. I still don't have a 4-th gear, but it's
so cold, that I will fix it after winter.

however I have another problem with car (colling fluid in oil). I will ask
about it in another thread.
